As a Roman imperial residence from antiquity, Trier’s old town has much to offer that is worth seeing. Although around 60,000 to 80,000 inhabitants already lived in what is officially Germany’s oldest city at that time, Trier’s old town is very manageable in terms of area. The most famous sights, which date back to both Roman times and the Middle Ages and are mainly of great historical significance, are therefore very close together. You should not miss the Trier Church of Our Lady, the Trier Cathedral and the imposing Roman city gate Porta Nigra, which is considered the landmark of the imperial city of Trier, on a tour of the historic old town of Trier.
